Purpose: Use mathematical models of Mixed Integer Linear Programming oriented to cellular distribution and aggregate production planning in order to obtain the appropriate product family for each manufacturing cell and from this, minimize production and material handling costs through the...

Few would challenge that terrorism, warlordism and organized crime—also known as the Deadly Trinity—could exhibit many similar characteristics but would they in any way be associated or even linked in a global proliferation network of weapons of mass destruction (WMD)? The case of the London...

BackgroundAs air pollution has been paid more attention to by public in recent years, effects and mechanism in particulate matter-triggered health problems become a focus of research. Lysosomes and mitochondria play an important role in regulation of inflammation. Interleukin-33 (IL-33) has been...

Flexible and wearable energy devices have become an important support and indispensable product of the era of artificial intelligence and Internet of Things. Enzyme biofuel cells (EBFCs) have received much attention for their ability to convert the body's abundant biochemical energy into...

Today's volatile market conditions in electronic industries have lead to a new production system, seru (which is the Japanese pronunciation for cell), and has been widely implemented in hundreds of Japanese and other Asia companies. In particular, the rotating seru has been widely implemented,...

In this paper, the effects of the hot-spotted cell on PV module were evaluated. The experimental observation was based on 100 kW PV array composed of 20 PV modules. It was found that an increasing number of hot-spotted solar cells in a PV module would likely increase its output power loss. It...

Purpose: In an increasingly competitive business environment, machine reliability problem merits special attention in operations of manufacturing cells. This is mainly due to flow line nature of the cellular layout, interdependency of downstream and upstream of machines related to each other....

Placement Assistance is one of the most important services that HEI's (Higher Educational Institutions) provide to their students. This assistance however will be active only if there is a constant interaction between the placement cell and students on continuous levels. Between, placement...

This paper presents a mathematical programming model for dynamic cell formation to minimize changeover-related costs (i.e., machine relocation costs and machine setup cost) and inter-cell material handling cost to cope with the volatile production environments in apparel manufacturing industry....

Machines are a key element in the production system and their failure causes irreparable effects in terms of cost and time. In this paper, a new multi-objective mathematical model for dynamic cellular manufacturing system (DCMS) is provided with consideration of machine reliability and...

A new multi-objective approach for the cell formation problem in a lumpy demand environment is presented. The objectives addressed in this paper are grouping efficiency and capacity requirements. In lumpy demand the required capacity is affected by demand variability and the correlation between...

The cell formation (CF) is one of the most important steps in the design of a cellular manufacturing system (CMS), which it includes machines’ grouping in cells and part grouping as separate families, so that the costs are minimized. The various aspects of the problem should be considered in a...

Heuristics based on dispatching rules are still widely used in practice as methods for effective scheduling systems. Despite the successful development of various novel dispatching rules for traditional job shop scheduling environments, nearly none of these has been applied to cellular...

Nowadays, with the increasing pressure of the competitive business environment and demand for diverse products, manufacturers are force to seek for solutions that reduce production costs and rise product quality. Cellular manufacturing system (CMS), as a means to this end, has been a point of...

Cell formation (CF) problem is one of the most important decision problems in designing a cellular manufacturing system includes grouping machines into machine cells and parts into part families. Several factors should be considered in a cell formation problem. In this work, robust optimization...

Auf der Hannover-Messe 2011 trat die Initiative "Industrie 4.0" an die Öffentlichkeit. Seither wird in Deutschland aktiv an der Vision Industrie 4.0 gearbeitet. Bisher gibt es hierzu nur fragmentarische Praxisbeispiele und gleichzeitig umfassende Bemühungen in der Grundlagenforschung. Dieses...

"Job Shop Lean integrates techniques from the Toyota Production System (TPS) that apply to high-mix low-volume with the science of Group Technology and Cellular Manufacturing (GT/CM) to replace those parts of the TPS that pertain solely to high-volume, repeatable processes. GT/CM is the...
